{Coastal erosion resistant submerged block with artificial reef function}

The present invention relates to a coastal erosion prevention submerged block having an inverted W-type artificial secondary function capable of vortexing and dispersion canceling in the course of structural natural collision of strong currents and waves moving in a nearby coast, Is an inverted W-shaped structure having a plurality of triangular cross-sections at different heights and is stable, and various types of seaweeds can be transplanted to the upper part. In addition, it is advantageous for attachment of seaweeds and aquatic organisms It is also possible to provide coastal fishing grounds with sea ranching as well as sea forests to prevent sparseness, and as a bio-symbiotic submerged block, basically a seawater communication effect and a reduction of crest transmission rate, To a coastal erosion resistant submerged block having the function of the present invention.

Generally, the block of the coastal erosion prevention block is installed in the coastal area of 5 ~ 30m in coastal area. In this submerged block, rapid seawater movement is attenuated and various seaweeds are adhered to grow, It is used as spawning grounds and sexually harvesting fry. In other words, since the upstream and downstream flows of the nutrients are carried over to the upper layer where the sunlight comes, with the terrain in the vicinity of the submerged block, the breeding of plankton becomes stronger in the upper layer, A good fishing ground is formed by gathering.

Most of the coastal erosion prevention submerged blocks that have been introduced have been constructed using concrete, and they are formed into a rectangular long tube or block shape, and on the outer surface thereof, a plurality of potholes are formed so as to allow the sea water to pass therethrough . However, such a submerged block has a problem that it is easily moved or tumbled by strong vortex or wave of seawater, and seaweed and the like adhere to the outer surface and become vegetated, so that there is a problem that it is easily separated by swirls or waves.

On the other hand, in the case of shellfish culture that artificially cultivate and propagate fish and shellfish, in particular shellfish culture, there is a project to release the seedlings, which are natural shellfish, to the sea. However, during the growth process, predators such as starfish, octopus, There was a plague in which the probability of being eaten and consumed was significantly lowered. Therefore, there is a need for artificial fishes, which are artificial structures that are installed on the sea floor for the breeding and promotion of fishery resources, and various types of submerged blocks, which are basically provided with artificial fishery function and coastal erosion prevention function, are introduced.

As a prior art related to the artificial fishes introduced in the past, the present invention is disclosed in Patent Registration No. 10-0754920 (artificial fishery for shellfish culture) and Patent Registration No. 10-0953619 (for tunnels for multifunctional artificial fishes for sea forest formation) Through the patent registration No. 10-0969232 (Improved irregular artificial reefs) and Utility Model Registration No. 20-0235846 (Artificial reefs in the middle of the sea), it is possible to prevent the coast from being eroded by abandoning the nearby coast, And aquatic organisms are formed to form a habitat for coastal ecosystem composition and resource composition.

On both sides of the projecting body in the longitudinal direction, In order to facilitate the attachment of seaweeds through the effect and increase of surface area, a large number of grooves, which are smaller inward, are formed. In order to reduce the velocity of wave crushing and algae movement, A through hole is formed, and the bottom is directly held against the bottom of the seabed and fixed In the bottom of the basket body, each recess receiving groove is formed.

In particular, a net-like vegetation basket is seated in a basket seating groove of a bottom body which is directly supported and fixed to the bottom of the seabed, and a mesh-like vestibule is fixed to the central ceiling of each of the projection bodies via an anchor bolt, There is a technical feature that the type fishing gear is installed at a certain height in the vegetation space.

According to the present invention, the coastal erosion preventive subblock block having the artificial fish function can provide a sea forest composition effect for restoration of aquatic ecosystem. This is because it has a wide surface area, It is also advantageous to settle and settle various kinds of adherent living organisms in the offset grooves, and the effect of the artificial rock forest formation on the sandy beach can be expected.

In addition, the fishery income increase effect can be provided by the increase of the population of the attached fish and the fish population, as well as the increase of the income of the fishermen, as well as various species (crustaceans, shellfishes, sea cucumbers) Of artificial seedling grafting is possible and can directly lead to increase of fishery income through internal farming facilities.

In addition, it is possible to provide a variety of supplementary effects, which can provide various underwater leisure sightseeing sites such as skin scuba, as well as relieving the coastal erosion due to the reduction of wave power through the fishing facilities.
